TTN_GETDISPINFO not send

[czerny]

Hallo,

this is a problem I am searching the error for hours now. It would be nice, if anyone could help!

I have a simple toolbar, composed of the standard bitmap (IDB_STD_LARGE_COLOR) with 15 Buttons and an own bitmap with 5 Buttons (120x24). I use 5 Buttons from the former bitmap, 3 separators and my 5 Buttons.

The toolbar is working ok. There is only one error: the tooltip from the very first button is not working. There is no TTN_GETDISPINFO notification send for this Button. All other Buttons have their tooltips.

A strange observation: If I use one more button as defined (and with luck the program is not crashing) all works ok?
Maybe this could be a hint .

I must have done a silly mistake.

Use TTN_GETDISPINFOW.

Dublicated id IDM_FILE_NEW ?

[jj2007]

It has nothing to do with your IDs. Tooltips don't send the ANSI notification, that's all.
Try something along these lines... and yes, I know it's assembler and this is a C forum.

  .if uMsg==WM_NOTIFY
      .if [ecx.NMHDR.code]==TTN_GETDISPINFOW
            lea edi, lvh
            invoke GetCursorPos, edi
            invoke ScreenToClient, hList, edi
            movi [edi.LV_HITTESTINFO.flags], LVHT_ONITEM
            invoke SendMessage, hList, LVM_HITTEST, 0, edi

Timovjl, you are my hero!!!

The most stupid errors take the most time.

Thank you jj2007, for your time.

Thank you jj2007, for your time.

Some time ago I wasted a lot of time chasing a problem with TTN_GETDISPINFO, and it turned out the control sent the Unicode version, but here I was obviously on the wrong track.

Some time ago I wasted a lot of time chasing a problem with TTN_GETDISPINFO, and it turned out the control sent the Unicode version, but here I was obviously on the wrong track.

My tooltips are string resources. I have tried to save the resource file as unicode file. There are non-ascii chars in the strings. But all is working with TTN_GETDISPINFO, ansi or unicode. Have you provided the strings directly?
What are your experiences? Are there at all drawbacks to save the rc file in unicode?

No drawbacks met so far. Attached is a sample app, the exe shows tooltips in several languages. Open the *.asc in Wordpad and scroll to the end to see how the rc file is structured. Search for SetLanguage and/or ToolTips to see relevant code.

Another example to use multilanguage menu/tooltips from resource with this function:

Code Select Expand

void SetLang(HWND hwnd, LANGID lid)
{
typedef LANGID (WINAPI *fnSetThreadUILanguage) (LANGID wReserved);
HMENU hMenu;
if ((GetVersion() & 0x00FF) > 5) // Vista =>
{
fnSetThreadUILanguage fnPtr = (fnSetThreadUILanguage)GetProcAddress(GetModuleHandle(TEXT("kernel32.dll")), "SetThreadUILanguage");
if (fnPtr)
(*fnPtr) (lid);
} else
SetThreadLocale(MAKELCID(lid, SORT_DEFAULT));
hMenu = GetMenu(hwnd);
SetMenu(hwnd, NULL);
DestroyMenu(hMenu);
hMenu = LoadMenu(GetModuleHandle(NULL), MAKEINTRESOURCE(2001));
SetMenu(hwnd, hMenu);
}EDIT: Fix for WinXP and Win8

The tooltips are working in english, russian and arabic, not in chinese (but thats a missing font). The label and editbox texts are only working in english.

Are there any non ascii characters in suomi?

[jj2007]

Another example...

Seems not to work, I see English only, and "Finnish" gets never checked. Win XP SP3...

[jj2007]

The label and editbox texts are only working in english.

Clicking "Pushme" or "Sayhi" shows something in the editbox. The rest is not implemented.

No problem with good old win2k!

Yes, but what it shows are black lines in all languages but english. See picture for russian.

I have installed simsun.ttf and wordpad shows now the chinese chars while your application shows still strings of undef chars.
